How to Check

Because this operation can be a

little difficult, the decision may be

made to have this done at the

dealership service department.

If the decision is made to perform

this operation, be sure to follow all

the instructions here, or a false

reading on the dipstick could result.

Notice: Too much or too

little fluid can damage the

transmission. Too much can

mean that some of the fluid could

come out and fall on hot engine

parts or exhaust system parts,

starting a fire. Too little fluid

could cause the transmission

to overheat. Be sure to get an

accurate reading if checking the

transmission fluid.

Wait at least 30 minutes before

checking the transmission fluid level

if the vehicle has been driven:

.

When outside temperatures are

above 32° C (90°F).

.

At high speed for quite a while.

.

In heavy traffic — especially in

hot weather.

.

While pulling a trailer.

To get the right reading, the fluid

should be at normal operating

temperature, which is 82°C to 93°C

(180°F to 200°F). Get the vehicle

warmed up by driving about

24 km (15 miles) when outside

temperatures are above 10°C

(50°F). If it is colder than 10°C

(50°F), drive the vehicle until the

engine temperature gauge moves

and then remains steady for

10 minutes.

A cold check can be made after the

vehicle has been sitting for eight

hours or more with the engine off,

but this is used only as a reference.

Let the engine run at idle for

five minutes if outside temperatures

are 10°C (50°F) or more. If it is

colder than 10°C (50°F), the engine

may have to idle longer. Should the

fluid level be low during this cold

check, the fluid must be checked

when hot before adding fluid.

Checking the fluid hot will give you

a more accurate reading of the fluid

level.

Checking the Fluid Level

Prepare the vehicle as follows:

.

Park the vehicle on a level

place. Keep the engine running.

.

With the parking brake applied,

place the shift lever in P (Park).

.

With foot on the brake pedal,

move the shift lever through

each gear range, pausing for

about three seconds in each

range. Then, position the shift

lever in P (Park).

.

Let the engine run at idle for

three minutes or more.
